Triphenyl-butin-1-yl-3-zinn, also known as triphenylbutyl-3-zinc, is an organozinc compound characterized by its molecular formula C21H19Zn. Triphenyl-butin-(1)-yl-(3)-zinn is a derivative of triphenylbutyl, where one of the hydrogen atoms is replaced by a zinc atom. It is typically used as a reagent in organic synthesis, particularly in reactions involving the formation of carbon-carbon bonds. Triphenylbutyl-3-zinc is known for its ability to act as a nucleophile in various organic transformations, such as cross-coupling reactions, where it can facilitate the formation of new carbon-carbon or carbon-heteroatom bonds. Its stability and reactivity make it a valuable tool in the synthesis of complex organic molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 4104-91-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,0 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4104-91:
(6*4)+(5*1)+(4*0)+(3*4)+(2*9)+(1*1)=60
60 % 10 = 0
So 4104-91-0 is a valid CAS Registry Number.

REGIO- AND STEREO-CHEMICAL FEATURES OF THE STANNYLCOPPER(I)-INDUCED SUBSTITUTION IN PROPARGYLIC SUBSTRATES

Ruitenberg, K.,Westmijze, H.,Meijer, J.,Elsevier, C. J.,Vermeer, P.

, p. 417 - 422 (2007/10/02)

Stannylcopper(I) species, R3SnCu and 2CuLi, preferentially convert propargylic substrates, R1CCCR2R3X (X=Br, MeCO2, MeS(O)O or MeSO3) into allenes R3Sn(R1)C=C=CR2R3.Only when the group R1 causes much greater steric hindrance than with R2 and R3 is the acetylenic product R1CCCR2R3SnR3 formed.The stereochemical course of the allene formation has been studied in both the steroid and non-steroid series, and found to be mainly or exclusively anti.
